Tessa said that the combined length of all 5 of her fingers on one hand should be less that 5 times the index finger. Tessa had the second shortest index finger. The combined length of all 5 of her fingers is less then what length? Show how you solved

5F < 5( X + x )

Step-by-step explanation:

Let each finger = F and

The index finger = X

The shortest index finger = x

the combined length of all 5 of her fingers on one hand should be less than 5 times the length of index finger

From the statement above, we get

5F < 5X

Tessa add the second shortest index finger.

That is

5F < 5( X +x)

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
